Parcel Inventory Mapping for a Land Trust

South Livermore Valley Area Plan
Update of Land Ownerships in the Tri Valley Region
Client:   The Tri-Valley Conservancy

Land trusts regularly need maps of their area that show owner boundaries and the character of the landscape. GreenInfo originally prepared poster maps of this data for a San Francisco Bay Area land trust, highlighting the trust's holdings as well as identifying other ownerships that are of strategic interest to the trust. Since the original work, GreenInfo has updated the maps reflecting changes in easement holdings and other local land changes.

The Tri Valley Conservancy (TVC) is an innovative land trust that was formed in the late 1980s in the area of Livermore Valley 70 miles east of San Francisco, California. TVC works to protect vineyards and other valuable open space in a crescent of land south of Livermore, and now in the surrounding areas.

GreenInfo has helped the land trust with a variety of GIS projects.  In this example, we developed a highly detailed base map for the land trust to use in envisioning and tracking its protected parcels and other ownerships of interest in its area of operations. The mapping involved aligning the land trust's holdings to ownership boundaries, clarifying ownership status and then developing an effective, large-poster sized base map that uses high resolution photography overlaid with parcel and other information.

We've also developed other thematic maps, covering acreage size ranges, habitat and other topics.

Results: The Tri Valley Conservancy has made extensive use of land ownership maps and related parcel level information.
